Football isn't played on paper, and whether you like it or not, the USA have a far better competitive record than Belgium over the past 10 years. It's all well and good having a wank over a teamsheet, but it means absolutely fack all if you can't even qualify for a tournament.
You're acting like Belgium would batter the USA 5-0 if they were to play each other in a competitive match right now, whereas I think a game like that would be a very close call.
Honestly, perhaps we should have this discussion if Belgium actually manage to qualify for their first tournament in over 10 years. Until then, they will remain European minnows with a shockingly bad record in recent times.
